When Mats Järlström's wife got snagged by one of Oregon's red light cameras in 2013, he challenged the ticket by questioning the timing of the yellow lights at intersections where cameras had been installed.

Since then, his research into red light cameras has earned him attention in local and national media—in 2014, he presented his evidence on an episode of "60 Minutes"—and an invitation to present at last year's annual meeting of the Institute of Transportation Engineers.

It also got him a $500 fine from the Oregon State Board of Examiners for Engineering and Land Surveying.

According to the board, Järlström's research into red light cameras and their effectiveness amounts to practicing engineering without a license. No, really. Järlström had sent a letter to the board in 2014 asking for the opportunity to present his research on how too-short yellow lights were making money for the state by putting the public's safety at risk.
